* On the left, you can control the various settings:
*Toggle the ''Enabled'' checkbox to enable/disable the {{{1}}}.
** '''Enabled:''' Click to enable the Frequency Counter input.
*Enter a ''Frequency Cutoff(Hz)'' and the {{{1}}} will ignore frequencies below the specified value.
** '''Timeout:''' How long the device will wait without detecting any pulses before reporting "0 Hz".

Frequency Counter

Double-click on the Frequency Counter object in order to run the example: [[Image:{{{1}}}_FrequencyCounter_Example.jpg|right|link=]]


General information about the selected object will be displayed at the top of the window. You can also experiment with the following functionality:

  • Toggle the Enabled checkbox to enable/disable the {{{1}}}.
  • Enter a Frequency Cutoff(Hz) and the {{{1}}} will ignore frequencies below the specified value.
  • Enter a filter type from the Filter Type drop-down menu. A Logic Level signal goes from alternates between 0 and VCC. A Zero Crossing signal goes from -VCC to VCC.
  • Modify the data interval value by dragging the slider. For more information on this setting, see the data interval page.
  • The Frequency label indicates the average frequency calculated from the pulses in the event so far.
  • The Total Count label indicates the total number of pulses since opening the example.
  • The Total Time label indiciates the total time in milliseconds that has elapsed since opening this example.
